UNITED STATES PATENT OFFICE;

ERSKINE A. COLE, OF CAMDEN, NEIV JERSEY, ASSIGNOR OF TIVO-THIRDS TOMORRIS FEIGEL AND LEOPOLD ROSENBUSH, OF NEIV YORK, N. Y.

SCUTTLE LOCK AND OPERATOR.

SPECIFICATION forming part of Letters Patent No. 458,730, datedSeptember 1, 1891.

Application filed April 17, 1891. Serial No. 389,392. (No model.)

To a/ZZ whom, t may concern/.-

Be it known that I, ERSKINE A. COLE, a citizen of the UnitedStates,residing at Camden, in the county of Camden and State of NewJersey, have invented a new and useful Device for Operating and Lockinga Scuitle-Lid, of which the following is a specification.

A vibrating plate and lever, the base of which is fastened to thecombing of a scuttle, are used for locking, unlocking, and operating thelid. A rope, bar, or other suitable device is attached to each end ofthe plate and as one side is depressed the other is raised and motionimparted through slots and a crankpin to the locking-bolts andlid-elevating lever.

On reference to the accompanying sheets of drawings, making part of thisspeciiication,

VFigure 1 is a side View of the device, the front end of the lid beingelevated and in section. Fig. 2 is the same view as Fig. l, with theexception that the front end of the sectioned lid is shown closed andthe mechanism reversed accordingly. Fig. 3 is a longitudinal side viewof the device. Fig. 4 is a longitudinal side view, the vibrating plateand lid-lifting lever being omitted. Fig. 5 is a plan view of the innerguides oit' the locking-bolts; and Fig. 6 is a perspective view of thedevice in place against the scuttle-combing, the lid being ele vated andpartly sectioned.

Similar letters refer to similar parts in the several views.

Fixed to the combing or side of a scuttle is the base A, to which theseveral parts of the device are attached. l

B, Figs. 3 and 4, is a projecting stub, on which moves a plate C aroundits reduction or stem a.

D D are slots in the plate C,each of which is composed of two slides orcurves, concenA tric ZJ, and eccentric or inclined b to the cen ter ofrotation of the stem a.

E are locking-bolts in guides F, xed to the base A oppositely of theplate C, beneath which their inner ends extend, and are provided withupwardly-projecting stems c and anti-friction rollers d for working inthe slots D D. Other guides G, Figs. 3, 4, and 5, are iixed to thebase-plate A, at the inner ends of the lockingbolts E, for preservingtheir rightn line motion and preventing the twisting and wabblingincident to the vibration of the plate O.

H is a lifting-lever which turns loosely around the stem a against theplate C. Its inner and short end has a curved slot e'for a project-ingcrank-pin f of the plate O, and its outer end engages with the hingedscuttlelid I for opening and closing it. To that end it is provided withan anti-friction roller J for reducing frictionai contact.

A rope, bar, or other suitable operating de vice K K is attached to eachend of the plate O. As one end of it is depressed by either rope theother is raised and motion imparted through the compound slots D D andthe crank-pin f to the bolts E and lever H.

In Fig. l the scuttle-lid I is shown open, supported on the end orroller J of the raised lifting-lever H and the bolts E drawn in.. The

vertical position of the lever for raising the lid is sustained by theend of its slot c, bearing against the crank-pin f. To close down andlock the lid, the cord K. is operated for depressing that side of theplate C and raising the other. Its vibration carries around thecrank-pin f and relieves the lever of its support, which graduallylowers by its own and the weight of the lid until it closes on the topof the scuttleI. Immediately thereafter the eccentric or inclined partsb of the slots D D engage with the stems c and slide the bolts E vintoengagement with the sides of the lid or downwardly-projecting staples L,fixed to it, dotted lines, Figs. 1 and 2. A contrary vibration of theplate C, by drawing on the rope K, reverses the mechanism for redraw ingthe bolts and again raising the lid.. The combined concentric andeccentric or inclined slots D D allow the bolts to remain at rest whilethe scuttle-lid is being opened or closed. Their construction andarrangement with respeci: to the lever-slot c is such that for open ingthe lid the eccentric curves b operate first by withdrawing the boltsand unlocking the lid. Then the lever-slot e, in connection with thecrank-pin f, vibrates the lever H and raises the lid. In closing the lidthe concentric curves allow the bolts to remain idle until it iscompleted.

IVhen it is desirable to employ an addi= tional fastening in the centerof the loose edge of the lid, ahook M can be fixed to the upper side ofthe plate Gand a staple N depended from the lid. It can be used aloneand the bolts E dispensed with. The same ropes K K operate the plate C,and the hook M and staple N are locked and unlocked by its oppositevibrations. The slots D D are used only with the bolts E, or when thebolts E and hook M are Worked together.

l. In a scuttle device, the combination, with a base and its projectingstem, of a vibrating plate on the stem, alifting-lever on said stem, theinner end of which is slotted for engagement with an actuating-pin ofthe vibrating plate and the outer end provided with an antifrictionroller, and means by which the vibrating plate is vibrated fo'roperating the lifting-lever and opening and closing the scuttle-lid.

2. In a scuttle device, the combination, with a base and its stein, of avibrating plate, a hook fixed to the vibrating plate and moving With it,a staple depending from the scuttlelid, and means by which the vibratingplate is vibrated for operating the hook` and lockn ing and unlockingthe scnttle-lid.

In testimony whereof l aix my signature in presence of two Witnesses.
